Alcatel Lucent OmniSwitch 6900-X48C6 - switch

The OmniSwitch 6900-X48C6 stands apart from conventional fixed-configuration switches by combining high-density 10 Gigabit Ethernet access with six 40/100 Gigabit Ethernet uplink ports in a compact 1U form factor. Built for modern enterprise and data centre edge deployments, it delivers wire-speed performance, advanced Layer 2/3 routing, and robust security without the complexity of chassis-based systems. Virtual Chassis technology allows up to eight units to be managed as a single logical switch, simplifying operations and enabling scalable, resilient network designs.

Highlights

• 48 x 1/10G SFP+ ports for flexible fibre connectivity
• 6 x 40/100G QSFP28 uplink ports for high-speed aggregation
• 1.44 Tbps switching capacity and 1071 Mpps forwarding rate
• Comprehensive Layer 2 and Layer 3 feature set including OSPF, BGP, VRRP, and PIM
• Support for VXLAN gateway and MPLS L3 VPN, VPLS, and VPWS
• Hot-swappable power supply bays and fan trays for redundancy and flexible airflow
• Advanced QoS with 8 hardware queues per port and WRED
• Robust security: ACLs, 802.1X, port security, DHCP snooping

In daily use

Deployed as an aggregation or top-of-rack switch, the 6900-X48C6 handles demanding workloads with ease. Its 256K MAC address table and support for up to 4094 VLANs ensure seamless segmentation in multi-tenant environments. Network administrators will appreciate the intuitive CLI, web GUI, and full SNMP support, as well as sFlow and OpenFlow integration for SDN environments. The dual hot-swappable power supply bays allow for redundant power configurations, while reversible fan trays support either front-to-back or back-to-front airflow to match data centre cooling schemes.
